10 being accidentally left in the tube or the slips being crumped orwrinkled or otherwise damaged to make the indicia thereon hard to read.

This invention also consists'in certain other features ofconstructionand in the'combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

erence will be had to the accompanying drawings, wherein like charactersdenote like or corresponding parts throughout the several views, and inwhich Figure 1 is an elevation of the improved tube.

Fig. 2 is a view showing the parts in a different position to show theslots for-receiving a part of the sales slip.

Fig. 3 is a view similar to Fig. 2, but showing the parts ina positionto show the registering openings for permitting money or the like to beplaced'in the tube.

Fig. 4 is a section on line 4-4: of Fig. 1.

Fig. 5 isfa view of the outer or transparent part with the end portionsattached thereto.

Fig. 6 is a view of the inner or metal tubewhich fits in part connectedthereto.

Fig. 7 is an elevation of the entire device showing the parts inpositionwhere one slot engages another.

Fig. 8 is a section on line 8-8 of Fig? 2. Fig. 9 is a section on line99 of Fig. 3. Fig. 10 is a section on line 10 of Fig. 1. In thesedrawings, the numeral 1 indicates the inner tube formed of metal andhaving an opening 2 therein and the numeral 3 indicates the transparentouter tube which is formed with the opening 4 which is formed with thenarrow extensions 4 at its ends. The inner tube 1 is formed with ahollow rib 5 which In describing the invention in detail, refis extendedinwardly and formed with a slot which opensout through the side of thetube for receiving a part of a sales slip A or other sheet shown indotted lines in Fig. 8. This rib also acts as reinforcing means for the5' metal tube and the extensions 4 of the opening 4 covers this slotwhen the parts are in a certain position, and as shown in Fig. 3 so asto facilitate the entrance of a part'of in the slot.

The openings 2 and 4 are of substantially the same size so that theywill permit money or the like to be placed in or removed from the devicewhen they are in registering position or nearly so, as shown in Fig. 3.The ends of the inner tube 1 are closed asshown in Fig. 4, and caps 6and 7 fit over the ends of both tubes and the tubes are held slightlyspaced apart by the end members 8 so that theslip or sheet A can fitbetween them and after a part of the slip is placed. in the slot withthe parts in position as shown in Fig. 2, a turning movement of one tuberelative to the other will wind the slip on the inner tube and under theouter tube, and as this outer tube is formed of transparent material theprinting or other matter on'the slip will be visible therethrough.

End pieces 9, formed of felt or the like, to snugly fit the conduits ofthe pneumatic system, are connected to the caps 6 and 7 'by the bolts orscrews 10 and one of these end pieces is connected to one end oftheinner tube 1 by the bolts as shown in Fig. 4:, but the other end issimply connected to the other end of the tube by a central bolt 11 sothat said other end piece is pivotally connected to said end of theinner tube.

the slip The corresponding end of the outer tube B is connected to thelast-mentioned end piece or to the cap 6, so that it will rotate whenthis end piece is rotated so that by holding one of the end piecesstationary and turning the other, one piece will rotate relaformed withthe recesses 12 for receiving the checks and should they tirely coveredwhich will make it difiicult to remove the slip.

Fig. 10 shows the parts with the stops in engagement and one end of theslip exposed. A leather washer 17 fits between one of the end pieces andthe cap 6 for increasing the suction action when the tube is placed inthe conduit.

Thus it will be seen that it is simply necessary to turn the parts tothe positions they so occupy in Fig. 2 and then insert part of the salesslip or other message carrying sheet into the slot and then by turningthe parts, the slip will be wrapped around the inner tube and under theouter tube as shown in Fig. 10

and if money or other matter is to be transported by the device, themoney or other object is placed in the device when the openings comeopposite each other as shown in Fig. 3. Asgwill be seen from Fig. 10,when the stops 15 and 16 are in engagement with each other, the openingswill be out of register, 80 that the money will be held in the deviceand a slip will be placed between the two tubes and one end partlyprojected.

The device is then placed in a conduit in the usual manner, but when itreaches the place for which it is meant, the operator at this place canreadily read the matter on the slip so thatno time is lost in sendingthe tube to.

- i the erson for which it is intended.

T e felt end pieces act as guides as well as bumpers, as the carrierleaves the pneumatic tube and falls in the receiver and if desiredarrows may be placed on the flanges of the caps 6 and 7 to indicate thedirection of turnin of the parts to wind the message into the tubecarrier.

This device also enables the operators .to more quickly see the siatures of the sales looking for fraudulent purchasers the detectivescould stand at the place where the tubes come throu h and quic 1y glanceat the handwriting an check to see if there is any handwriting they arelooking for and the could quickly go to the department from w ich thetube was sent before the purchaserbecomes nervous due to an delay.

, s it is now the detectives must wait unml til the tubes are relayed totheauthorizers and sort through the duplicate O. K.d sales checks goingto one girl and then another looking at the handwriting. By the timeitis foundenough time has elapsed to allow the purchaser to receive the O.K.d stub and be on her way before the arrival of the de tective in thedepartment.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily a parent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended clalms.

Having thus described our invention, what we claim as new is 1. Acarrier tube for a pneumatic tube system comprising inner and outercylinders having openings therein, the outer c linder being formed oftrans arent materia rings placed between the end portions of thecylinders for slightly spacing them apart, means for rotating onecylinder in relation to the other, and means for attaching a part of asales slip or the like to the inner cylinder whereby the slip will bewrapped on the inner cylinder and under the outer cylinder, when onecylinderis rotated with respect to the other.

2. A carrier tube for a pneumatic tube system comprising inner and outercylinders having openings therein, the outer cylinder being formed oftransparent material, means for rotating one cylinder in relation to theother, means for attaching a part of a sales slip or the like to theinner cylinder whereby the slip will be wrapped on the inner cylinderand under the outer cylinder, when one cylinder is rotatedwith respectto the other, such means comprising an internal rib formed. on the.inner cylinder and providing a slot extending outwardly for receiving apart of the slip.

3. A carrier tube for a pneumatic tube system comprising inner and outercylinders having openings therein for permitting access into theinnercylinder,the outer cylinder being" formedof transparent material, endpieces, one of which is connected to the inner cylinder and the other tothe outer cylinder, said end pieces being formed of felt or the likeandof greater diameter than the cylinders, spacer ri 'laced between theend portions of the cy ind ers for slightly spacing them apart, andmeans on the inner cylinder for detachabl' receiving an endof a sli orsheet whereby said slip or sheet will e wrapped around the inner cyliner under the outer cylinder when one cylin er isrotating with respect tothe other.

4. A carrier. tube for a pneumatictube system comprising inner and outercylinders having openings therein for permitting access into the innercylinder, the outer cylinder beingformed of transparent material,endpieces, one of which is connected to the inner cylinder and the otherto the outer.

cylinder, said end pieces being formed of felt or-th'e like andgreater-diameter than the tures.
